G0486/G0487 Wide Belt Sander -31-
NOTICE
The table has been adjusted at the fac-
tory and should require no further attention.
However, we recommend verifying that it is
parallel with the sanding roller.
The oscillation speed of the sanding belt is
adjustable. Different oscillating speeds yield dif-
ferent sanding results. We recommend trying
various speeds on a scrap piece of wood similar
to the final workpiece.
To adjust the oscillation speed:
1. Loosen the lock nut on the speed control
adjustment knob ( Figure 30).

2. Turn the knob clockwise to decrease the
oscillation speed and counterclockwise to
increase it.
3. Tighten the lock nut loosened in Step 1 to
secure the knob.

The corners of the table can be independently
adjusted up or down. By disconnecting the chain
and turning the pertinent table elevation screw
sprocket, (
Figure 31) table parallelism can be
achieved.
Adjusting the table parallelism can be a very
tedious task that takes a great amount of patience.
DO NOT adjust the table unless you are having
trouble sanding your workpiece to a uniform
thickness.
If a table adjustment is needed, take precise
notes on the positioning of the table elevation
screws. This will allow the original setting to be
re-established.
